Mitchell Buford ordered the Type-07 Supergun to be destroyed, as it could shell Tokyo and Seoul from its location. He sent the mercenary and a small force of South Koreans to destroy the artillery titan.

It was a hornets nest with NK soldiers, armored vehicles and artillery emplacements, which were destroyed by the mercenary. The mercenary cleared the path to the supergun using cunning and deadly force.

Later the mercenary ordered in a Cruise Missile Strike on the gun after destroying the jammer device interferring with their support options. The Jack of Diamonds, Ji An, had appeared to have survived the destruction of the titan weapon, but was later verified by the mercenary. The whole fortress base was later captured by South Korean forces.
